Key Features
-
Double vane structure advantage: Adopts mature double vane design to reduce the force of vanes pressing against the stator inner surface, reduce wear, and improve the pump’s service life and stability under low to medium pressure working conditions.
-
Ultra-compact and efficient: Smallest volume in the same series, specially designed for equipment with limited installation space; Volumetric efficiency up to 93% or more, effectively converting mechanical energy into hydraulic energy and reducing energy loss.
-
Stable and low-noise operation: Concentric rotor and stator design, built-in oil trapping prevention structure, ensuring smooth operation and low noise; Wide operating temperature and viscosity range, strong adaptability to small-sized hydraulic system working conditions.
